CONSIDERATIONS CONCERNING EARTHQUAKE RESPONSE ANALYSIS OF ROCKFILL DAMS.

The earthquake response of rockfill dams is strongly influenced by various assumptions concerning the fill behavior and excitation mechanism. Starting from the results obtained for some Romanian dams, the paper emphasizes the influence of material dynamic properties and nonsynchronous excitation along the dam foundation. Also, the earthquake behavior of a large rockfill dam during the Vrancea earthquake, on the 4-th of March 1977, is shown.
